A brake pressure control system for use as an antiskid braking control system, for example, for a motor vehicle, detects a skidding condition of a wheel of the motor vehicle based on a rotational speed of the wheel and a speed of the motor vehicle. A braking pressure applied to the wheel is increased and reduced according to control gradients, respectively, and the control gradients are continuously controlled so that the detected skidding condition will approach a target skidding condition. Times in which the braking pressure is continuously increased and reduced, respectively, are counted, and the control gradients are corrected depending on the counted times.
